Abstract
A power supply includes a load connected in series with a switch. The power supply uses the load in series with the switch to maintain a substantially constant voltage. The voltage may be used as a voltage bias and supplied to a controller module that is used to control switching of the switch. The load is operable to maintain a substantially constant voltage at an input terminal of the load and also to function as a current sink. The load may also perform an additional function, such as provide auxiliary lighting or operate as a cooling mechanism for the power supply and/or a lighting system that includes the power supply.
